Uri uri = new Uri("ms-appx:///assets/data.json");

var storageFile = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(uri);

using (var storageStream = await storageFile.OpenReadAsync())
{
    using (Stream stream = storageStream.AsStreamForRead())
    {
        using (StreamReader reader = new StreamReader(stream))
        {
            var jsonText = reader.ReadToEnd();
            var results = JsonConvert.DeserializeObject<DemoData>(jsonText);
            this.DataContext = results;
        }
    }
}

I’ve got a file called data.json stored in an Assets folder:

And the file’s Build Action is set to Content:

Change the value passed to the Uri constructor and … the file will be loaded successfully. Once loaded, I used the strongly typed generic DeserializeObject method to convert the Json data to a class called DemoData.

Liquid Exception: incompatible character encodings: IBM437 and UTF-8 in css.html

My solution was to temporarily change the code page to UTF-8:

chcp 65001

This temporarily changes the code page of the current Command window to UTF-8.

The setup:

• Windows 8
• Visual Studio 2012, .NET 4.5,
• ASP.NET MVC web application
• Non domain-joined computer (it’s on my home network)
• Using a Microsoft account (FKA Live ID) as the local account
• Using IIS Express/IIS
• Windows Authentication Enabled
• Anonymous Logon Disabled

<system.webServer>
    <security>
        <authentication>
            <windowsAuthentication enabled="true" />
            <anonymousAuthentication enabled="false" />
        </authentication>
    </security>
</system.webServer>

While there are a few proposed solutions, this is the only one that worked for me so far.

1. Start Internet Explorer
2. Click the settings Menu
3. Select Internet options
4. Click the Security tab
5. Select Local intranet
6. Click Sites
7. Click Advanced
8. Add http://localhost/ to the Local intranet zone
9. Close.
10. Verify it’s now working.

Done.

Alternatives welcomed. :)

You might try FindName to discover it doesn’t work. That’s because it’s not recursive.

So, I created a simple extension method to do the same thing:

public static class FrameworkElementExtensions
{
    public static FrameworkElement FindDescendantByName(this FrameworkElement element, string name)
    {
        if (element == null || string.IsNullOrWhiteSpace(name)) { return null; }

        if (name.Equals(element.Name, StringComparison.OrdinalIgnoreCase))
        {
            return element;
        }
        var childCount = VisualTreeHelper.GetChildrenCount(element);
        for (int i = 0; i < childCount; i++)
        {
            var result = (VisualTreeHelper.GetChild(element, i) as FrameworkElement).FindDescendantByName(name);
            if (result != null) { return result; }
        }
        return null;
    }
}

The code above loops through the children and attempts to match by name.

A simple usage (admittedly, this is stupid and clunky as lists are often virtualized, but …)

private void Page_Loaded_1(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
    for (int i = 0; i < myPeeps.Items.Count; i++)
    {
        var element = myPeeps.ItemContainerGenerator.ContainerFromIndex(i) as FrameworkElement;
        if (element != null)
        {
            var tb = element.FindDescendantByName("tbValue") as TextBlock;
            if (tb != null)
            {
                tb.Text = i.ToString();
            }
        }
    }
}

Given this DataTemplate and Page:

<Page.Resources>
    <local:SampleDataSource x:Key="sampleData" />
    <DataTemplate x:Key="SampleDataTemplate">
        <Grid >
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
            </Grid.RowDefinitions>
            <TextBlock HorizontalAlignment="Left" Text="{Binding Name}" />
            <TextBlock Grid.Row="1" Name="tbValue" />
        </Grid>
    </DataTemplate>
</Page.Resources>

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}" 
      DataContext="{StaticResource sampleData}">
    <ItemsControl x:Name="myPeeps"
        ItemsSource = "{Binding Persons}"
        ItemTemplate="{StaticResource SampleDataTemplate}" FontSize="22"/>
</Grid>

And this sample data:

public class Person {
    public string Name { get; set; }        
}    

public class SampleDataSource {
    public IEnumerable<Person> Persons { get; private set; }
    
    
    public SampleDataSource () {
        var list = new List<Person>();
        
        list.Add(new Person { Name = "Alex" });
        list.Add(new Person { Name = "Betsy" });
        list.Add(new Person { Name = "Carla" });
        list.Add(new Person { Name = "Donald" });
        list.Add(new Person { Name = "Erica" });
        list.Add(new Person { Name = "Francis" });            
        
        this.Persons = list;
    }            
}

You’ll get results like this:
